Application filed March 9,

- To all whom'z't may concern:

'Be it known that I, DAVID H. EVANS, a citizen of the United States, residing atMilbank, county of'Grant, South Dakota, have invented new and useful Improvements in Joint-Chairs, of which the following is-a specification.

The present invention relatesto improve ments in means for connecting the meeting ends of two railway rails, the primary object of the same being to provide a simple, strong and effective joint which will support the rails against vertical movement and effectively sustain the same in alinement.

Another object of the invention is to provide a joint chair for the meeting ends of two rails which shall have its base formed with lugs that engage within recesses in the base flanges of the rails and which shall be provided with a detachable side or fish plate that is hingedly connected with the base of the chair, whereby the device may be easily and quickly applied to or detached from the rails.

With the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claim.

In the drawings: Figure l is aperspective view of two rails connected in accordance with the present invention, Fig. 2 is a transverse sectional view taken in a line with one of the bolts, Fig. 3 is a vertical longitudinal sectional view on the line 3-3 of Fig. 2, Fig. 4 is aperspective view looking toward the underface of one of the rails, Fig. 5 is a perspective view of the chair section of the joint, and Fig. 6 is a similar view of the de tachable side nlate. 1

Referring now to the drawings in detail, the numerals 11 indicate the meeting ends of. two railway rails of the ordinary construction, These rails have their base flanges, upon their underfaces, each cen trally provided with one or more substantially rectangular depressions forming pockets 2. The rails have their webs provided with the usual transverse openings for the reception of thesecuring elements which are of the ordinary construction being in the nature of nuts and bolts therefor.

The numeral 3 designates the chair memher for the joint. This member includes a horizontally straight base 4 which is centrally provided with a plurality of centrally Specification of LettersjPatent.

arranged longitudinally extending elongated lugs 5, the said lugs being spaced in the transverse center of the base and corresponding'in number with the pockets 2 upon the underfaces of the rails, and the said lugs are adapted to be snugly received within the said pockets. The base upon one of its longitudinal edges is formed with a vertical extension 6 which is adapted to contact with the longitudinal edges of the base flanges of therails upon one SiClQ'Of said rails, and formed with the extension is an angular flange 7, the said flangeoverlying the base the base flanges vertically from the flange 7 is a plate 8, the said plate being received within the fishing spaces of the rails and having itsupper edges contacting with the underfaces of the heads of the rails. The plate 8 is provided with openings which register with the elongated bolt openings in the through which the referred to securing means pass. The opposite longitudinal edge of the base 3 is formed with an inturned portion which I term indicated by the numeral 9, and the said base, adjacent the outer wall of the tongue is provided with a plurality of substantially rectangular openings 10.

Theremovable side plate is indicated by the nruneral 11 and comprises a vertical member 12 which is adapted to contact with the webs of the rails and have its upper edge engage with the underface of the heads of the rail.

The numeral 13 designates an angular flange which is formed upon the lower edge of the plate 12, the said flange engaging with the base flanges said flange 13 terminates in a downturned substantially vertical longitudinally extending portion 14 which engages with the longitudinal edges of the rails. Formed upon the lower edge of the said portion 14 is a plurality of hook-shaped lips or knuckle members 15 corresponding in number with the openings in the base of the chair member, and the said hooks are adapted to be received within the said openings so that the side plate 11 is detachably hinged to the base plate. The vertical plate 12 is provided with openings to receive the above referred to securing elements, and as the lugs 5 are snugly received within the pockets 4, it will be noted that the same assist webs of the rails and a tongue and which is.

- Copies of this patent may be obtained for the joint members in preventing both the lateral and longitudinal movement of the rails. The length of said lugs, however, does not equal the length of the pockets and soprovides for the contraction and eX- pansion of the rails at the joint. The lugs also reinforce the base of the joint, adding to the strength thereof,-so that a vertical movement of the rails at the joint will be resisted by the securing elements of the side plates of the joint sections and the reinforced base.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the ad\'*antages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus I claim is: I

In combination with" the meeting ends of described the invention, What two rail sections, plates secured within the fishing spaces of the said rails, angular flanges formed on each of said plates and engaging the top face of the base flanges of said rails, a chair formed on the edge of one of said flanges and extending to the opposite edge of said face, an inwardly rolled longitudinal edge formed upon the chair, the said chair being provided at intervals with openings adjacent said rolled edge, a series of hook shaped lips formed upon the flange of the opposite plate for engagement with the said openings, the said lips contacting with the outer surface of the inwardly rolled flange when the plates are inposition.

In testimony whereof I afiix my signature in presence of two witnesses.

DAVID H. EVANS.
